Saint-Martin-de-Corléans (Aosta): new remarks on the megalithic area (Neolithic- Bronze age), Appendix: radiocarbon dating analyses of the post and stele alignments phase
No full textGli AA presentano alcune osservazioni di
approfondimento sui risultati degli studi pluridisciplinari
svolti, a partire dall’ampia documentazione
delle ricerche condotte da Franco
Mezzena negli anni 1970-1990 sull’area
megalitica di Saint-Martin-de-Corléans. Gli
studi rientrano in un progetto, coordinato dalla
Soprintendenza di Aosta e da un Comitato
scientifico incaricato tra il 2008 e il 2018 di
seguire la valorizzazione del sito e curarne
una edizione scientifica.
Il quadro riassuntivo di ricostruzione storica
conferma ed evidenzia come Saint-Martinde-
Corléans sia un sito-chiave per la comprensione
delle azioni di strutturazione e vita
di un luogo di culto e cerimoniale neolitico che
nel tempo viene trasformato in area funeraria.
La verifica qui esposta sulla sequenza cronologica
e le successioni delle azioni succedutisi
nell’area megalitica a partire dall’aratura,
primo intervento nella metà/fine del 5 mill.
A.C., confermano e completano quanto illustrato
nel volume recentemente edito. Gli approfondimenti
sui rituali funerari propongono
un primo inquadramento nel contesto delle
aree che si sviluppano a Nord e Sud delle Alpi.
L’area megalitica di Aosta per la ricchezza di
documentazione e il potenziale informativo
assume una maggiore importanza anche alla
luce delle recenti ricerche sviluppatesi intorno
all’arco alpino.The Authors present some in-depth observations
on the results of the multidisciplinary
studies carried out, starting from the extensive
documentation of the research conducted
by Franco Mezzena in the years 1970-1990,
on the megalithic area of Saint-Martin-de-
Corléans.
The studies are part of a project coordinated
by the Aosta Superintendency and by a Scientific
Committee in charge, between 2008
and 2018, of monitoring the valorisation
of site and of editing a scientific publication.
The synthetic framework of the historical reconstruction
proposed for the megalithic area
confirms and highlights how Saint-Martinde-
Corléans is a key site for the understanding
of the structural actions and the lifetime of a
Neolithic cult and ceremonial site that over
time was transformed into a funerary area.
Here we confirm the assessment of the chronological
sequence and the succession of actions
that took place in the megalithic area starting
from the ploughing action, identified as
the first intervention which took place in the
middle/end of the 5th mill. B.C.. The paper
integrates the results presented in the recently
published book.
The studies on funerary rituals allows the site
to be integrated into a wider context in the
regions north and south of the Alps. Recent
developments in research on circum-Alpine
megalithism confirm the leading position of
the site of Aosta, by the richness of its documentation
and its potential to provide informatio

Holocene vegetation dynamics and human impact at tree line in the Central Swiss Alps (Patiéfray, 2341 m a.s.l, Bagnes, Valais)
No full textL'étude palynologique menée dans le marais de Patiéfray ( Val de Bagnes, Valais, 2341 m alt. ) permet de restituer l'évolution de la végétation sur près de 11'000 ans. Les alentours du marais sont recolonisés vers 9950 - 9450 cal BP ( aroles, mélèzes et bouleaux ). Dès 7'500 BC des occupations mésolithiques sont archéologiquement attestées dans les environs. Au début de la période néolithique, l'impact humain est peu visible dans le diagramme, mais dès 4150 cal BP, ( 2220 cal BC ), la limite supérieure de la forêt s'abaisse et des prairies à mélèzes se développent. A l'époque romaine, cette limite s'abaisse encore et de nouvelles essences cultivées apparaissent à basse altitude ( Castanea sativa, Juglans regia ). Dès le 5e siècle de notre ère, l'agriculture s'intensifie et l'estivage en altitude se développe. Les résultats des analyses paléobotaniques concordent bien avec ceux des recherches historiques et archéologiques menées dès 2006 pour restituer l'évolution des occupations dans le haut Val de Bagnes ( projet ITRES ).Die vorliegende Studie verbindet Resultate aus Paläoökologie und Archäologie. Die Analyse der Mikro - und Makrofossilien ermöglicht es, die Vegetations - und Feuergeschichte der letzten 11'000 Jahre zu rekonstruieren. Die Gegend um Patiéfray wurde um 9950 - 9450 cal BP (8000 - 7500 J.v.Chr.) durch Arven, Lärchen und Birken wiederbewaldet. Diese lichten, mit Vaccinium Arten und Zwergwachholder durchsetzten Wälder boten gute Lebensbedingungen für mesolithische Jäger und Sammler, deren Präsenz durch archäologische Funde in einem Felsabris am Standort belegt ist. Mit dem Beginn der Weidewirtschaft in der Jungsteinzeit verstärkte sich der menschliche Einfluss auf die Vegetation im Gebiet nur leicht. Deutlich nahm der menschliche Einfluss in der Region anfangs Bronzezeit zu (4150 kal. J. BP; 2200 J.v.Chr.). Die Waldgrenze unterhalb von Patiéfray sank, es etablierten sich Lärchenwiesen. In der Römerzeit sank die Waldgrenze weiter und in den Tälern wurden neue Kulturpflanzen (Edelkastanie, Walnuss) angebaut. Ab dem 5. Jh. n.Chr. intensivierte sich die Land - und Alpwirtschaft. Die durch die paläoökologische Studie gewonnenen Resultate stimmen gut mit den in der Region durchgeführten archäologischen Prospektionsarbeiten (Projekt ITRES) überein, deren Ergebnisse in diesem Beitrag zusammengefasst werden.The present study combines results from paleoecology and archeology. We analyzed pollen, plant macrofossils and charcoal to reconstruct the vegetation and fire history of the past 11000 years. Around 9950 - 9450 cal BP (8000 - 7500 cal. BC) the Patiéfray area was affforested by stone pines, larches and birches, interspersed with Vaccinium species and dwarf juniper. These open forests provided good conditions for Mesolithic hunter - gatherers, whose presence is attested by archeological finds in a rock shelter at Patiéfray. With the onset of pastoralism in the Neolithic period, human influence on vegetation increased slightly in the area. Anthropic impacts in the region increased significantly only at the beginning of the Bronze Age (4150 cal. BP; 2200 cal. BC). Timberline below Patiéfray sank, (sub -) alpine meadows scattered with larch trees became established at the site. In the Roman period, timberline further decreased and new crops (sweet chestnut, walnut) were cultivated down in the valleys. From the 5th century AD both, agriculture and alpine summer farming intensified. The results of the paleoecological study are consistent with the archeological prospection work carried out in the region (ITRES project
Scenari ricompositivi ed esperienze di valorizzazione dell’Area megalitica di Saint-Martin-de-Corléans ad Aosta
No full textLa musealizzazione del sito di Saint-Martin-de-Corléans ha offerto la possibilità di contestualizzare i dati sito-specifici in un quadro
territoriale più ampio e di evidenziare le relazioni tra la storia dell’uomo e le trasformazioni del paesaggio. Presentiamo qui l’approccio
metodologico impiegato per la realizzazione degli “scenari ricompositivi” presentati nel prodotto multimediale proiettato su grande
schermo all’interno del percorso museale dell’Area megalitica. La ricomposizione delle informazioni archeologiche e paleoambientali
risulta utile sia per fini scientifici che per fini espositivi, in cui la percezione della storia integrata del paesaggio diventa più intellegibile
quando realizzata in modo evocativo.Recompositive scenarios and experiences of valorisation of the megalithic area of Saint-Martin-de-Corléans in Aosta
The musealization of the site of Saint-Martin-de-Corléans offered the chance to contextualise site-specific information in a wider
territorial framework and to highlight the relationships between human history and environmental changes. Here we present the methodological
approach used to produce “recompositive scenarios” displayed in the multimedia product screened in the museum itinerary of
the Megalithic Area. Merging archaeological and paleoenvironmental information is useful both for scientific and exhibition purposes,
where the perception of an integrated history of landscapes becomes intelligible when evocatory.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
